In the illustrative embodiment, the monocoque 200 combines what wouldtraditionally be formed from one or more separate structures (e.g., oneor more body components and one or more frame components) into asingle-piece, monolithic structure. As such, any vehicle of the presentdisclosure incorporating the monocoque 200 does not include an internalchassis or frame structure that supports separate body components (e.g.,panels, doors, etc.). Due at least in part to consolidation of body andframe components into an integrally-formed structure, the illustrativemonocoque 200 may be associated with, or otherwise facilitate, improvedmanufacturability and/or simplified maintenance compared to otherconfigurations.

Depending on the particular vehicle type and monocoque configuration,one or more dimensions of the intermediate section 230 of the monocoque200 may vary. In one example, the intermediate section 230 may have afirst length associated with, and defined by, a small intermediatesection mold unit (e.g., the mold unit 832 shown in FIG. 8). In thatexample, the first length of the intermediate section 230 may at leastpartially define a stowage compartment of a 650 cubic feet deliveryvehicle (e.g., the vehicle 120). In another example, the intermediatesection 230 may have a second length associated with, and defined by, amedium intermediate section mold unit (e.g., the mold unit 834 shown inFIG. 8). In that example, the second length of the intermediate section230 may at least partially define a stowage compartment of a 1000 cubicfeet delivery vehicle (e.g., the vehicle 130). In yet another example,the intermediate section 230 may have a third length associated with,and defined by, a large intermediate section mold unit (e.g., the moldunit 836 shown in FIG. 8). In that example, the third length of theintermediate section 230 may at least partially define a stowagecompartment of a 1200 cubic feet delivery vehicle (e.g., the vehicle150).

Furthermore, depending on the particular vehicle type and monocoqueconfiguration, the intermediate section 230 of the monocoque 200 may beomitted entirely. In such embodiments, the front cage 210 and the rearfloor 220 may be integrally-formed as a single-piece, monolithicstructure without the intermediate section 230 interposed therebetween.It should be appreciated that the utility vehicles 110 and 140 may eachinclude a monocoque formed without the intermediate section 230, atleast in some embodiments.

Referring now to FIG. 3, a vehicle 300 incorporates the monocoque 200with the intermediate section 230 arranged between the front cage 210and the rear floor 220. Additionally, the vehicle 300 includes a cabhood 302 arranged above the front cage 210 to enclose the operator cabin212 and a stowage compartment 310 arranged rearward of the front cage210 and the cab hood 302. In the illustrative embodiment, the stowagecompartment 310 is at least partially defined by the intermediatesection 230 and the rear floor 220 and has a roof 312 and sidewalls 314.The illustrative vehicle 300 may be similar to any one of the vehicles120, 130, 150 discussed above, at least in some embodiments.

Because the monocoque 200 has a composite construction as indicatedabove, it should be appreciated that any vehicle described herein thatincorporates the monocoque 200 (e.g., any of the vehicles 110, 120, 130,140, 150, 300, 500) incorporates a composite structure (e.g., thestructure 700 shown in FIG. 7). In the case of the vehicle 300, each ofthe intermediate section 230, the roof 312, and the sidewalls 314 isformed from composite materials and has a composite structure, at leastin some embodiments. In those embodiments, each of the intermediatesection 230, the roof 312, and the sidewalls 314 does not includemetallic material.

Referring now to FIG. 4, a prior art delivery vehicle 400 includes astowage compartment 410. The stowage compartment 410 includes a floor412, a pair of sidewalls 414, a ceiling 416, and a refrigeration unit418 at least partially housed by the stowage compartment 410 andconfigured to cool the stowage compartment 410. The rear end of thevehicle 400 includes a landing 404 and a step 406 that leads to thefloor 412 of the stowage compartment 410.

As depicted in FIG. 4, the landing 404 has a landing height 424 aboveground level 402 and the step 406 has a step height 426 above thelanding 404. The floor 412 has a floor height 422 above the ground level402 that includes both the landing height 424 and the step height 426.Typically, the landing height 424 is about 25 inches, the step height426 is about ten inches, and the floor height 422 is about 35 inches.

Referring now to FIG. 5, a delivery vehicle 500 may include a monocoque(e.g., the monocoque 200) described above with reference to FIG. 2.Furthermore, in some embodiments, the vehicle 500 may be similar to oneor more of the vehicles 120, 130, 150 described above. In any case, theillustrative delivery vehicle 500 includes a stowage compartment 510having a floor 512, a pair of sidewalls 514, and a ceiling 516, as wellas a refrigeration unit 518 housed by the stowage compartment 510.Unlike the prior art delivery vehicle 400, however, the vehicle 500lacks a step corresponding to the step 406. As such, the floor 512 has afloor height 522 that substantially corresponds to, and may be equal to,the landing height 424. The floor height 522 may be less than thirtyinches, such as in the range of 22 to 28 inches, for example. A pair ofwheel wells 530 formed within the stowage compartment 510 are offsetfrom one another by a separation distance 532. In certain embodiments,the separation distance 532 may be about 50 inches.

In some cases, the prior art delivery vehicle 400 suffers from one ormore disadvantages not associated with the illustrative vehicle 500. Inone respect, the sidewalls 414 and the ceiling 416 of the prior artvehicle 400 are typically formed of metallic material such as aluminum,for example, which is a poor thermal insulator. As such, the compartment410 may be poorly insulated and have a tendency to adopt the temperatureof the ambient environment relatively quickly. That may be especiallythe case in the summer when radiant heat from the sun supplements theambient hot air to exacerbate the warming of the compartment 410. Incontrast, the sidewalls 514 and the ceiling 516 of the illustrativevehicle 500 are formed of composite materials, which exhibit superiorinsulating characteristics compared to metallic material such asaluminum. Accordingly, the compartment 510 is insulated from the ambientenvironment to a greater degree than the compartment 410. Thatinsulation may be particularly advantageous in cases in which thevehicle 500 is a refrigerated vehicle such as a food delivery vehicle,for instance. It should be appreciated that the insulating properties ofthe compartment 510 may ease the cooling burden on the refrigerationunit 518 and thereby increase performance of the refrigeration unit 518.Additionally, in certain circumstances, increased performance of therefrigeration unit 518 may enable the vehicle 500 to be provided with asmaller refrigeration unit 518 than would typically be required by theprior art vehicle 400.

Another drawback associated with the prior art vehicle 400 is theelevated nature of the floor 412 relative to the ground level 402. Itshould be appreciated that the elevated floor 412 is not merely a designchoice but rather a feature often necessitated to accommodate inclusionof the internal chassis or frame, the powertrain, and associatedcomponents. Put another way, to accommodate the mounting of aconventional internal combustion engine and other powertrain components(e.g., a transmission, transaxle, and/or a differential) to an internalchassis, the floor 412 is elevated above the ground level 402 by thefloor height 422. Consequently, the elevated floor 412 reduces thestorage capacity and/or volume of the stowage compartment 410 andrequires the provision of the step 406. Delivery personnel using thevehicle 400 must therefore step up onto the landing 404 and ascend thestep 406 in order to access the compartment 410.

The illustrative vehicle 500 obviates a number of the aforementioneddisadvantages by eliminating the necessity of the elevated floor 412.Due in part to the provision of the monocoque 200 as a single-piece,monolithically formed structure having a relatively lightweightcomposite construction, and due in part to the absence of powertraincomponents typically provided in other configurations (e.g., a centraldrive shaft beneath the underside 214 of the monocoque 200 that providesa rotational input to a differential), the floor 512 need not beelevated above the ground level like the floor 412. As a result, thevehicle 500 allows increased stowage capacity of the stowage compartment510 to be achieved without raising the ceiling 516. Moreover, because astep similar to the step 406 may be omitted from the vehicle 500, thefloor height 522 corresponds to the landing height 424 of theconventional vehicle 400, and delivery personnel may avoid the effort ofascending both the landing 404 and the step 406 to access the stowagecompartment 510 of the vehicle 500. Notably, it should be appreciatedthat a rear bumper of the vehicle 500 may be slightly lower than thefloor 512 and that delivery personnel may access the compartment 510 byfirst stepping on the rear bumper. In some embodiments, the rear bumpermay have a height of about 20 inches above the ground level, whereas thefloor 512 may have a height of about 25 inches above the ground level.

Referring now to FIG. 6, in the United States, trucks are oftenclassified according to their gross vehicular weight rating (GVWR).Those truck classifications, the associated duty classifications, andthe corresponding GVWRs are illustrated in the table 600. In theillustrative embodiment, one or more of the vehicles 110, 120, 130, 140,150 has a GVWR (i.e., accounting for the weight of the truck when emptyand the payload carrying capacity of the truck when full) of between6,000 pounds and 19,800 pounds. In some embodiments, one or more of thevehicles 110, 120, 130, 140, 150 has a GVWR of between 10,001 pounds and14,000 pounds such that one or more of the vehicles 110, 120, 130, 140,150 is embodied as, or otherwise includes, a Class 3 truck. In oneparticular example, in some embodiments, the 1000 cubic foot capacityvehicle 130 weighs roughly 6,500 pounds when empty and has a 6,000 poundpayload capacity such that the vehicle 130 has a GVWR of about 12,500pounds. Of course, it should be appreciated that in other embodiments,the vehicle line 100 may include one or more vehicles in Class 3, one ormore vehicles in Class 4, and/or one or more vehicles in Class 5.

In some embodiments, the systems and methods described herein may findparticular utility in connection with delivery vehicles in Classes 3through 5. For example, the methods 1000, 1100, 1300 described below maybe utilized to form a monocoque for a delivery vehicle having a GVWRbetween 10,001 pounds and 19,500 pounds. The stowage capacity of such avehicle may be between 450 cubic feet and 1200 cubic feet. In certainembodiments, the stowage compartment (e.g., the compartment 510) of thevehicle may be isolated from the operator cabin (e.g., the operatorcabin 212) of the vehicle.

Referring now to FIG. 7, any vehicle of the present disclosure includesa monocoque having the composite structure 700. In the illustrativeembodiment, the composite structure 700 incorporates one or morerelatively lightweight, low-density materials to impart a relativelylightweight construction to the vehicle. As discussed below, theillustrative composite structure 700 includes one or more of thefollowing: balsa wood, plastic, fiberglass, resin, Kevlar, honeycomb,and carbon fiber. The composite structure 700 does not include, and isnot formed from, metallic material, at least in some embodiments. Inthose embodiments, the monocoque (e.g., the monocoque 200) incorporatingthe composite structure 700 does not include metallic material.

The illustrative composite structure 700 includes a core 702 and a shell704 that at least partially surrounds the core 702. In the illustrativeembodiment, the core 702 is formed from balsa wood and/or one or more ofthe following composite, non-metallic materials: unidirectionalfiberglass, multi-directional fiberglass, Kevlar, carbon fiber, plastic,honeycomb, or other suitable composite, non-metallic materials. Ofcourse, in other embodiments, the core 702 may be formed from othersuitable materials to provide a relatively lightweight construction tothe composite structure 700. The illustrative shell 704 is formed fromfiberglass and resin. However, in other embodiments, the shell 704 maybe formed from other suitable materials. Additionally, in theillustrative embodiment, the composite structure 700 includes a laminatelayer 706 that at least partially covers the shell 704.

It should be appreciated that the composite structure 700 used to formthe monocoque of any vehicle of the present disclosure offers a numberof advantages over multi-piece metallic constructions of conventionalvehicles. In one respect, the single-piece monolithic structure formedwith the composite structure 700 has fewer parts and offers greaterstructural simplicity than vehicle constructions requiring multipleparts. In another respect, the structural simplicity afforded by thecomposite structure 700 may facilitate maintenance and improvestructural efficiency. In yet another respect, due to a lack of metallicmaterial, the composite structure 700 may minimize or eliminate rustand/or corrosion and thereby have a service life that exceeds theservice life of vehicles having conventional constructions. In someinstances, monocoques incorporating composite structures 700 consistentwith the teachings of the present disclosure may have service lives of20 years or more.

Referring now to FIGS. 8 and 9, a modular mold system 800 (see FIG. 8)includes a number of illustrative mold units that may be selected andarranged to form a monocoque system 900 (see FIG. 9). It should beappreciated that when arranged to form the monocoque system 900, theselected mold units of the modular system 800 are utilized to form amonocoque such as the above-described monocoque 200, for example.Furthermore, it should be appreciated that similar reference numerals inthe 800 and 900 series are used to designate corresponding features ofthe modular mold system 800 and the monocoque system 900.

The illustrative mold system 800 includes a front cage mold unit 810, arear floor mold unit 820, and a plurality of intermediate mold units 830having a small intermediate section mold unit 832, a medium intermediatesection mold unit 834, and a large intermediate section mold unit 836.As discussed below, each of the mold units 810, 820, 832, 834, 836 has amold cavity having a size and a shape corresponding to a correspondingfeature of the monocoque system 900 such that subsequent to introductionof the composite materials (e.g., the materials of the compositestructure 700) into the mold cavity, the corresponding feature of themonocoque system 900 will be formed. Accordingly, the front cage moldunit 810 includes a front cage mold cavity 912 that has a size and ashape corresponding to the front cage 910 of the monocoque system 900(and also the front cage 210). The rear floor mold unit 820 includes arear floor mold cavity 922 that has a size and a shape corresponding tothe rear floor 920 of the monocoque system 900 (and also the rear floor220). The intermediate mold units 832, 834, 836 include respectiveintermediate mold cavities 933, 935, 937 each having a size and a shapecorresponding to the respective intermediate section 932, 934, 936 ofthe monocoque system 900 (and also the intermediate section 230).

As evident from FIGS. 8 and 9, each of the intermediate mold units 832,834, 836 is sized for positioning between the front cage mold unit 810and the rear floor mold unit 820 to form the monocoque system 900. Itshould be appreciated that any one of the intermediate mold units 832,834, 836 may be selected and arranged between the front cage mold unit810 and the rear floor mold unit 820 to form the monocoque system 900.Selection of the particular mold unit 832, 834, 836 is based on theconfiguration of the vehicle and the monocoque included therein, asfurther discussed below.

In the illustrative embodiment, the front cage mold cavity 912 of thefront cage mold unit 810 has an opening 914 at a rear end thereof (i.e.,the end closest to one of the intermediate sections 932, 934, 936 asshown in FIG. 9) to establish a fluidic coupling between the cavity 912and another component of the mold system 800. In some embodiments, afluidic coupling may be established between the front cage mold cavity912 and one of the intermediate mold cavities 933, 935, 937 when thefront cage mold unit 810 is arranged contiguously with one of thecorresponding intermediate mold units 832, 834, 836. Additionally, insome embodiments, a fluidic coupling may be established between thefront cage mold cavity 912 and the rear floor mold cavity 922 when thefront cage mold unit 810 is arranged contiguously with the rear floormold unit 820.

In the illustrative embodiment, the rear floor mold cavity 922 of therear floor mold unit 820 has an opening 924 at a front end thereof(i.e., the end closest to one of the intermediate sections 932, 934, 936as shown in FIG. 9) to establish a fluidic coupling between the cavity922 and another component of the mold system 800. Each of theintermediate mold cavities 933, 935, 937 of the intermediate mold units832, 834, 836 has an opening 938 at a front end thereof (i.e., the endclosest to the front cage 910 as shown in FIG. 9) and an opening 940 ata rear end thereof (i.e., the end closest to the rear floor 920 as shownin FIG. 9). When one of the intermediate mold units 832, 834, 836 isarranged contiguously with the front cage mold unit 810, a fluidiccoupling is established between the corresponding intermediate moldcavity 933, 935, 937 and the front cage mold cavity 912 via the openings914, 938. Additionally, when one of the intermediate mold units 832,834, 836 is arranged contiguously with the rear floor mold unit 820, afluidic coupling is established between the corresponding intermediatemold cavity 933, 935, 937 and the rear floor mold cavity 922 via theopenings 924, 940.

It should be appreciated that the front end of each of the illustrativeintermediate mold units 832, 834, 836 is configured for directconnection and attachment to the rear end of the front cage mold unit810. Furthermore, it should be appreciated that the rear end of each ofthe illustrative intermediate mold units 832, 834, 836 is configured fordirect connection and attachment to the front end of the rear floor moldunit 820. Consequently, when any one of the intermediate mold units 832,834, 836 is directly connected with the front cage mold unit 810 and therear floor mold unit 820, the front cage mold cavity 912, thecorresponding intermediate mold cavity 933, 935, 937, and the rear floormold cavity 922 are fluidically coupled to one another in a contiguousarrangement to establish a continuous monocoque mold cavity into whichcomposite materials may be introduced to form the monocoque as asingle-piece, monolithic structure.

It should also be apparent that the rear end of the illustrative frontcage mold unit 810 is configured for direct connection and attachment tothe front end of the rear floor mold unit 820. As a result, when thefront cage mold unit 810 is directly connected to the rear floor moldunit 820, the front cage mold unit 810 and the rear floor mold unit 820are fluidically coupled to one another in a contiguous arrangement toestablish a continuous monocoque mold cavity into which compositematerials may be introduced to form the monocoque as a single-piece,monolithic structure.

In the illustrative embodiment, the small intermediate section mold unit832 has a length L1 as suggested by FIG. 9. The medium intermediatesection mold unit 834 has a length L2 that is greater than the lengthL1, at least in some embodiments. The large intermediate section moldunit 836 has a length L3 that is greater than the length L2 and thelength L1, at least in some embodiments.

In some embodiments, the small intermediate section mold unit 832 may beused to form the intermediate section 932 of the monocoque system 900such that the monocoque at least partially produced using the mold unit832 is included in a vehicle having a storage volume of 650 cubic feet(e.g., the vehicle 120). Additionally, in some embodiments, the mediumintermediate section mold unit 834 may be used to form the intermediatesection 934 of the monocoque system 900 such that the monocoque at leastpartially produced using the mold unit 834 is included in a vehiclehaving a storage volume of 1000 cubic feet (e.g., the vehicle 130). Insome embodiments still, the large intermediate section mold unit 836 maybe used to form the intermediate section 936 of the monocoque system 900such that the monocoque at least partially produced using the mold unit836 is included in a vehicle having a storage volume of 1200 cubic feet(e.g., the vehicle 150).

Referring now to FIG. 10, an illustrative method 1000 of forming amonocoque (e.g., the monocoque 200) using a modular mold system (e.g.,the system 800) is depicted. The method 1000 corresponds to, or isotherwise associated with, performance of the blocks described below inthe illustrative sequence of FIG. 10. It should be appreciated, however,that the method 1000 may be performed in one or more sequences differentfrom the illustrative sequence. Furthermore, it should be appreciatedthat one or more of the blocks described below may be executedcontemporaneously and/or in parallel with one another. In someembodiments, the method 1000 may be performed manually by one or moreoperators. In other embodiments, the method 1000 may be embodied as, orotherwise include, a set of instructions that are performed by anautomated control system.

The illustrative method 1000 begins with block 1002. In block 1002, theoperator(s) or the control system selects a land vehicle type or amonocoque configuration for a particular land vehicle. It should beappreciated that to perform block 1002, the operator(s) or the controlsystem may select any vehicle envisioned by the present disclosure orany monocoque configuration associated with a particular vehiclecontemplated by the present disclosure. From block 1002, the method 1000subsequently proceeds to block 1004.

In block 1004 of the illustrative method 1000, the operator(s) or thecontrol system selects a first mold unit of the modular mold systembased upon the selected vehicle type or monocoque configuration. In theillustrative embodiment, to perform block 1004, the operator(s) or thecontrol system selects the rear floor mold unit 820 of the modularsystem 800 in block 1006. However, in other embodiments, it should beappreciated that block 1004 may be performed by selecting (i) the smallintermediate section mold unit 832 (i.e., in block 1008), (ii) themedium intermediate section mold unit (i.e., in block 1010), or (iii)the large intermediate section mold unit 836 (i.e., in block 1012).Selection of one of the intermediate mold units 832, 834, 836 as thefirst mold unit is described in greater detail below with reference toFIG. 11. In any case, from block 1004, the method 1000 subsequentlyproceeds to block 1014.

In block 1014 of the illustrative method 1000, the operator(s) or thecontrol system couples the selected first mold unit to the front cagemold unit 810 of the modular system 800. It should be appreciated thatto perform block 1014, the selected first mold unit (i.e., the rearfloor mold unit 820) is coupled to the front cage mold unit 810 suchthat the front cage mold cavity 912 is fluidly coupled to the rear floormold cavity 922 to at least partially establish a continuous monocoquemold cavity. Following performance of block 1014, the method 1000proceeds to block 1016.

In block 1016 of the illustrative method 1000, the operator(s) or thecontrol system introduces one or more composite materials (e.g., thecomposite materials included in the composite structure 700) into thecontinuous monocoque mold cavity formed in block 1014. Morespecifically, to perform block 1016, at least in some embodiments, theoperator(s) or the control system performs blocks 1018, 1020, and 1022.In block 1018, the operator(s) or the control system introduces one ormore composite materials into the continuous monocoque mold cavitywithout introducing metallic material into the cavity. In otherembodiments, however, block 1018 may be omitted from the method 1000. Inblock 1020, the operator(s) or the control system places a firstmaterial in the continuous monocoque mold cavity. The first material mayinclude balsa wood and/or plastic, at least in some embodiments. Inblock 1022, the operator(s) or the control system places a secondmaterial different from the first material in the continuous monocoquemold cavity. The second material may include fiberglass and resin, atleast in some embodiments. Following performance of block 1016, themethod 1000 proceeds to block 1024.

In block 1024 of the illustrative method 1000, the operator(s) or thecontrol system cures the one or more composite materials in thecontinuous monocoque mold cavity to form the monocoque. To perform block1024, the operator(s) or the control system may perform blocks 1026,1028, and 1030, at least in some embodiments. In block 1026, theoperator(s) or the control system forms a core (e.g., the core 702)including the first material introduced in block 1016. In block 1028,the operator(s) or the control system forms a shell (e.g., the shell704) including the second material introduced in block 1016 that atleast partially surrounds the core. In block 1030, the operator(s) orthe control system forms a laminate layer (e.g., the layer 706) that atleast partially covers the shell.

Referring now to FIGS. 11 and 12, an illustrative method 1100 of forminga monocoque (e.g., the monocoque 200) using a modular mold system (e.g.,the system 800) is depicted. The method 1100 corresponds to, or isotherwise associated with, performance of the blocks described below inthe illustrative sequence of FIGS. 11 and 12. It should be appreciated,however, that the method 1100 may be performed in one or more sequencesdifferent from the illustrative sequence. Furthermore, it should beappreciated that one or more of the blocks described below may beexecuted contemporaneously and/or in parallel with one another. In someembodiments, the method 1100 may be performed manually by one or moreoperators. In other embodiments, the method 1100 may be embodied as, orotherwise include, a set of instructions that are performed by anautomated control system.

The illustrative method 1100 begins with block 1102. In block 1102, theoperator(s) or the control system selects a land vehicle type or amonocoque configuration for a particular land vehicle. It should beappreciated that to perform block 1102, the operator(s) or the controlsystem may select any vehicle envisioned by the present disclosure orany monocoque configuration associated with a particular vehiclecontemplated by the present disclosure. From block 1102, the method 1100subsequently proceeds to block 1104.

In block 1104 of the illustrative method 1100, the operator(s) or thecontrol system selects a first mold unit of the modular mold systembased upon the selected vehicle type or monocoque configuration. In theillustrative embodiment, to perform block 1104, the operator(s) or thecontrol system performs one of blocks 1106, 1108, and 1110. In block1106, the operator(s) or the control system selects the smallintermediate section mold unit 832. In block 1108, the operator(s) orthe control system selects the medium intermediate section mold unit834. In block 1110, the operator(s) or the control system selects thelarge intermediate section mold unit 836. Following performance of block1104, the method 1100 proceeds to block 1112.

In block 1112 of the illustrative method 1100, the operator(s) or thecontrol system selects a second mold unit of the modular system. In theillustrative embodiment, to perform block 1112, the operator(s) or thecontrol system performs block 1114. In block 1114, the operator(s) orthe control system selects the rear floor mold unit 820 of the modularsystem 800. From block 1112, the method 1100 subsequently proceeds toblock 1116.

In block 1116 of the illustrative method 1100, the operator(s) or thecontrol system couples the selected first mold unit to the front cagemold unit 810 of the modular system 800. It should be appreciated thatto perform block 1116, the selected first mold unit (i.e., one of theintermediate mold units 832, 834, 836) is coupled to the front cage moldunit 810 such that the front cage mold cavity 912 is fluidly coupled tothe corresponding intermediate mold unit cavity (i.e., one of thecavities 933, 935, 937) to at least partially establish a continuousmonocoque mold cavity.
